潜艇自航模水声定位系统的设计与实现

摘要

To meet the demands of the submarine target positioning in self-propelled model experiment ,a set of under-water acoustic positioning system is designed and implemented according to a certain type of submarine self -propelled model . Combined with certain acoustic receiving and launching hardware ,the goal of real-time data acquisition ,processing ,testing of underwater target is achieved .The system also possesses the functions such as sensor delay calibration ,track display ,da-ta storage ,and can solve the problems such as multichannel data acquisition synchronization and abnormal points .Finally , the comparison between acoustic positioning and GPS trajectory shows that the underwater acoustic positioning system can realize the accurate two-dimensional positioning of self-propelled model .%为满足潜艇自航模试验中目标定位的需要，针对某型潜艇自航模型设计和实现了一套水声定位系统。系统结合水声接收、发射等相关特定硬件设备实现了对水中目标数据实时采集、处理、监测。系统还具有传感器延时标定、数据实时采集处理、轨迹显示、数据存储等功能，对多通道数据采集同步、野点修正等问题进行了处理。最后通过对比水声定位系统轨迹与 GPS 轨迹，结果表明，该水声定位系统能够实现对自航模型的精确二维定位。
